Gasket Compression in Metal Housings and Assemblies

Gasket CompressionGasket compression in metal housings and assemblies can support sealing or contribute to gasket failure. That’s because rubber gaskets are resilient, but only to a point. Compressing a gasket within allowable limits forms a reliable seal. When a gasket is over-compressed, however, the rubber won’t rebound when the compressive stresses are removed. This creates a gap between the gasket and the surface of the housing or assembly. Gaps cause leaks, and seals that leak won’t support your designs.

Material scientists calls the permanent deformation of the gasket material “compression set”, a term that’s used widely but not always fully understood. Engineers need to know the basics of compression set, but they also need to consider its limitations as a test method. With housings and assemblies, it’s essential to account for the entire application environment, including variables such as temperature and vibration. Relaxation, a related phenomenon, is also associated with gasket compression. (more…)

Rubber Gate Seal for Water Filtration System Lasts Longer, Resists Disinfection, Adds Business Value

Water Filtration Case StudyWhen a manufacturer of water filtration systems needed a rubber gate seal that would last longer and resist ultraviolet (UV) light, Elasto Proxy provided a value-added solution. This custom gasket doesn’t just resist exposure to water, contact with metal and concrete, and disinfection with UV light. The gate seal also supports ease-of-installation and is ready to ship from Elasto Proxy’s warehouse in Newmarket, Ontario.

The 60-durometer EPDM lip seal (J-seal) that Elasto Proxy provides attaches to the bottom of a metal gate used in water treatment facilities. This rubber seal is also compressed against hard concrete floors and exposed to a range of temperatures. UV disinfection kills waterborne microbes that can make people sick, but ultraviolet light can also degrade rubber materials. Without reliable sealing and strong bonding, gaskets like this can’t meet business or technical requirements.

To provide a complete sealing solution, Elasto Proxy leveraged its expertise in seal design, material selection, custom fabrication, warehousing, and logistics. (more…)

Skylight Seals and Load Requirements

Skylight SealsSkylight seals from Elasto Proxy can meet requirements for dead loads, live loads, local maintenance loads, and wind compression loads.

Skylights are windows that are installed in a building’s roof or ceiling. They admit natural light, support passive solar heating, and provide a visual connection to the outdoor environment. Skylights feature large spans of glass, but there’s more to these windows than meets the eye. Glass loads can be heavy, and wind loads can add weight and pressure to skylight panels. If heavy loads cause a skylight to collapse, people can get hurt. Serious damage to a building’s interior can result, too. (more…)

Rubber Door Seals for Walk-In Bathtubs

Walk-in BathtubsWalk-in bathtubs allow people with limited mobility to bathe themselves safely and independently. Typically, they’re used in hospitals, healthcare settings, retirement communities, and assisted living facilities. Unlike a traditional bathtub, a walk-in bathtub has a door on the front or side of the unit. This allows users to enter and exit the tub without having to lift their legs over the side. This reduces the chance of slip-and-fall injuries, and also supports wheelchair accessibility.

Walk-in bathtubs feature various door designs and come with various capabilities. Hydrotherapy options include whirlpools and adjustable bubble jets. Units with adjustable shower heads, integral handrails, LED lighting, and inside-the-tub seating are also available. Many walk-in bathtubs now include fast-draining capabilities so that users don’t need to remain in the unit for long periods of time while the bathtub empties. Product features vary, but all walk-in bathtubs need reliable rubber door seals. (more…)

Case Study: Rubber Hatch Seals for Military Ground Vehicles

military vehiclesRubber hatch seals for military vehicles don’t just keep out wind, water, dirt, and mud. They need to withstand extreme temperatures and various weather conditions. Hatch seals must avoid compression set, too. If a vehicle’s hatch causes a rubber seal to over-compress, the part won’t provide proper sealing. Ultimately, this permanent deformation creates a gap and causes seal failure. That’s bad news for military vehicles and the highly-trained personnel who operate them.

In this case study from Elasto Proxy, you’ll learn how we solved a sealing challenge for a manufacturer of military vehicles. The rubber hatch seals that we supply resist over-compression and demonstrate the value that we add to defense contracts. For our 25 years, Elasto Proxy has been an important link in the military supply chain. Elasto Proxyalso holds a Controlled Good Certificate (CGC) and works closely with trade groups such as the Canadian Association of Defense and Security Industries (CADSI). (more…)

Custom Skylight Seals Case Study

Custom Skylight SealCustom skylight seals need to meet demanding environmental and load testing requirements. When a skylight company faced a sealing challenge, Elasto Proxy provided the perfect solution on a tight timetable.

Skylights are specialized windows that builders install in a roof or ceiling. They admit natural light, provide a visual connection to the outdoor environment, and support passive solar heating. Skylights can help reduce energy costs, but their benefits go beyond sustainability. For example, the giant domed skylights found atop some commercial buildings are designed to enhance the occupants’ overall experience. By combining art with infrastructure, these complex structures truly illustrate the art of sealing. If a skylight fails, however, property damage and personal injury may result. (more…)

Rubber Gate Seals for Water Filtration Systems

Rubber Gate Seals from Elasto Proxy
Rubber Gate Seals from Elasto Proxy

In this case study, you’ll learn how Elasto Proxy provides complete sealing solutions to manufacturers of water filtration systems. Rubber gate seals start with seal design and compound selection, are crafted with water jet cutting and infrared splicing, and add value with inventory management and shipping.

In wastewater treatment plants, metal gates are bolted to concrete frames to control flow and channel the effluent for disinfection. To prevent leakage, a rubber seal is fitted to the bottom of the frame. This seal attaches to the gate with bolts, and must withstand prolonged exposure to water and contact with a concrete base. In water filtration systems that use ultraviolet (UV) light, UV resistance is essential.

When a manufacturer of water filtration systems wanted a custom gate seal, Elasto Proxy provided more than just a replacement part. First, our solutions providers listened to the manufacturer’s requirements and analyzed all of their needs. Our technical team then applied its expertise in compound selection, and identified a seal design that could solve the manufacturer’s specific sealing challenge.

Next, our skilled production personnel in Boisbriand, Quebec used water jet cutting and infrared (IR) splicing to craft a custom sealing solution. Yet that’s not where this case study ends. Today, Elasto Proxy stocks rubber gate seals for water filtration systems at our warehouse in Newmarket, Ontario. To meet our partner’s business requirements, we ship quantities according to their annual sales forecasts. (more…)

Foam Pads for Vacuum Lifters in Stone Countertop Manufacturing

Foam PadsIn this case study, you’ll learn how Elasto Proxy helped a stone countertop manufacturer solve a material handling challenge. By applying our technical design, compound selection, and custom fabrication expertise, we provide the protective pads used in vacuum tools that move quartz slabs.

Stone countertop manufacturing is a complex process. First, raw materials are fed into special mixers and blended together. The mixture is then poured into a mold and formed into slabs of various sizes. After the stone slabs are compacted, they’re moved to a curing kiln and heated for ultimate strength and stability. Polishing, quality assurance, and labeling complete the stone countertop manufacturing process.

When a leading manufacturer of quartz countertops asked Elasto Proxy for assistance with a material handling challenge, our solutions providers studied the requirements for a foam pad that helps move slabs into a 200° F kiln. This elastomeric pad attaches to the vacuum tooling and protects both the tool and the slab. High-temperature resistance and compression set are essential, but so is resistance to suction loss since the stone slabs are so heavy. (more…)
